Answer:
Heterotrophs
Explanation:
Heterotrophs are organisms that are not able to form their own source of energy and are dependent on others to gain energy. Most of the algae are autotrophs which uses light energy to make organic energy source.
Some algae are heterotrophs that do not require sunlight and pigments as they do not make their food on their own and utilize sugars manufactured by other plants and algae.
They are also called colorless algae as they do not possess pigments. These heterotrophic algae are consumers, not producers. Therefore the correct answer is heterotrophs.
Digging burrows.
Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear.
Rtks can activate the enzyme phosphoinositide 3-kinase, which phosphorylates inositol phopholipids; these phospholipids then serves as docking sites that recruit specific intracellular signaling proteins to the plamsa membrane. RTKs may activate various pathways including; the MAP-kinae signalling module, the Ras signalling pathway, and the phospholipase C/inostol phospholipid signaling pathway.
